Easy to install and use air heater with a 5-30 kW single-row heat exchanger with air stream flow up to 5300 m3/h. Equipped with energy-efficient EC motor with stepless speed control.

The EC motor option ensures maximum efficiency at reduced speed, which for our clients means saving electricity, and thus funds, at the same efficiency compared to similar devices powered by AC motors.

By paying less than the average price of similar devices on the market, our clients receive a high-performance device that will heat any room using only access to a hot water source (heat pump, heater, water installation). The device's performance is confirmed, among other things, by a 5-year warranty unprecedented on the market (with replacement of the device for a new one) and a lifetime warranty on the housing.

In addition, the SonnEC water heaters, thanks to EC motors, are quiet, which allows for them to be installed in a place where a normal working day takes place. The heaters are not so quiet to provide heating comfort e.g. in an office, where silence is especially required, but nevertheless, they are ideally suited for interiors such as sports halls, warehouse halls, garages, party rooms etc.

However, if the building is large and high, and the wall insulation leaves a lot of room for improvement, our stronger heaters will work better (sonnEC 3 and sonnEC 4).

Here are the proofs of the best quality:

  • Modern design and universal colors are made for creating nice background for your business
  • EC motors allows you to not worry about the costs of maintenance
  • Less energy means less CO2 released into the atmosphere
  • Unbeatable price and service will make you sure of the choice
  • 5 years warranty for units and exchange your device one by one in door-to-door system will keep you safe
  • Life-time warranty for the casing – because we are sure that they will serve you even longer without any discoloration or damage
  • European motors and German provider are the proofs of the tradition and quality
